Sharpnose Pufferfish GALLERYCanthigaster rostrata
They are named for their ability to inflate themselves to several times their normal size by swallowing water or air when threatened. They have small, almost sandpaper-like spines. The Sharpnose is a small fish of only about 4 inches in length when full grown. Look for them hiding near erect sponges and sea plumes, mangrove roots and sea grass beds.
